Abstract: The present invention relates to a device for removing contaminant particles in a plasma process and methods thereof. More specifically, the present invention relates to a device for operating a plasma processing chamber and a method thereof. The method for operating a plasma processing chamber includes a step of performing a plasma process under process pressure and with process power for generating plasma. When a first ramping-down stage starts, the process power and the process pressure are substantially ramped down into a middle power level and a middle pressure level in the first ramping-down stage at the same time. The middle power level and the middle pressure level are preselected to increase a plasma sheath boundary above a critical height from a surface of a substrate. To move one or more contaminant particles to an edge outside of the substrate, purge gas moves from a shower head assembly at the rate high enough to sweep far contaminant particles trapped in plasma. When a second ramping-down stage starts, a middle power level and a middle pressure level are reduced into a zero level and base pressure in the second ramping-down stage.
